84. Susan Lyne

After Susan left her CEO spot at Martha Stewart in June, observers assumed she’d end up at a big media company: After all, she’s best known for her long tenure at ABC. So it was a surprise to see her land at Gilt, the high-fashion, invitation-only e-shopping site that lets people buy designer clothes at bargain prices. The New York-based startup, launched in November 2007, now has 65 employees and generates an average of $70,000 in revenue for every 2-3 day sale.
